Technical Abstract

A recording tape cartridge having a recording tape; a leader member attached at the top of the recording tape; a single reel on which the recording tape is wound; a housing holding the reel rotatably and having an opening from which the tape is wound out and a holding portion adjacent to the opening; and an urging member urging and securing the leading member at the holding portion when the recording tape is taken back in the housing; the urging member having a pressing portion formed continuously in the axial direction of the leading member and contacting both ends of the leading member when the leading member is held at the holding portion. Equal force is applied to the both ends of the leading member. Therefore, the leading member does not slant and a chucking member of the tape drive securely chucks the leader member.
